KNF NFB 30 KPDC-B Liquid Pump
Low Pulsation

Every KNF NFB boxer-type liquid pump features two modes of operation, each offering cost-saving potential.

In parallel mode, the alternating pump head operation results in a smooth, even flow of media – significantly reduce the pulsation, making it a valid replacement for gear pumps.

Two in One

In individual mode, the NFB diaphragm pumps can transfer two different liquids at the same time, ultimately saving your space and money.
